Comparative Study of Peanut Oil (Arachis hypogea) Produced in Andouria Brand Factories and that Produced Artisanally by Women in Kelo (Chad)

This study aims to evaluate the nutritional quality of the oil produced by Andouria brand factories and that produced in an artisanal manner by women in Kélo in Chad. Ten samples each of the Spanish coarse grain variety were used to produce oil by Andouria women and factories. The parameters studied are the Humidity Index, Impurity Index, Acidity Index, Saponification and Peroxide Index. The methods used are as follows: Humidity Index (ISO-662, 2016) [10], Impurity Index (ISO-663, 2007) [9], Acidity and Acid Index (ISO-660, 2020) [7], Saponification Index (ISO-365, 2002) and Peroxide Index (ISO-3960, 2007) [8]. The results show that the Humidity Index of Artisanal oil varies from 0.08 to 0.179 and that of Andouria oil between 0.11 to 0.22; the Impurity Index of Artisanal oil varies from 3.19 to 5.48 and that of Andouria oil varies from 3.09 to 6.28; the Acid Value of Artisanal oil varies from 3.25 to 15.31 and that of Andouria oil varies from 1.34 to 23.43; the Impurity Index of Artisanal oil varies from 3.19 to 5.48 and that of Andouria oil varies from 3.09 to 6.28; the acid value of artisanal oil varies from 3.25 to 15.31 and that of Andouria oil varies from 1.34 to 23.43. These results show that several parameters are 100% compliant such as the Humidity Index of Andouria oil, the Impurity Index of Artisanal oil, the Saponification Index of Andouria oil and the index of Andouria oil Peroxide. Others, on the other hand, present non-compliance: 10% of the Impurity Index of Andouria oil, 60% of the Acidity Index of Artisanal oil and 50% of Andouria oil, 10 % of the Saponification Index of the Artisanal oil, 10% of the Peroxide Index of the Artisanal oil. From all of the above, we can conclude that the parameters obtained as well as the extraction conditions show that these two oils are of good nutritional quality.
